MAG is very close to 1048 noise wise, maybe even less noise, however just as Cathar states, there is a vibration concern, which could lead to noise.
DD is an OEM customer, but like many, they are awaiting more pumps
We are running 3 shifts, 24-7 trying to meet back orders before our shut down for the expansion.
We also have a new injected cases, plastic for pump chamber housing, and alloy injection with PVD coating for drive section.
Will be out Aug/Sept
Here is kind of a cool pic I took the other day for a reviewer, showing what is under "the cap"

The whole motor is encased in thermal conductive material for additional liquid, thermal, and noise protection.
